PromptDock — PDF Crop & Extract for ChatGPT

About

romptDock docks a clean panel onto ChatGPT so you can work through PDF question banks without ever taking a screenshot.
 
WHAT IT DOES
 
📄 Upload once, reuse anytime
Load a PDF and it's automatically saved to your local library — reopen it instantly next time, no re-uploading.
 
✂️ Crop straight into the chat box
Drag over any question in the PDF preview and it's sent directly into ChatGPT as an image — no screenshot tool, no clipboard juggling. Works cleanly at any zoom level, and auto-scrolls as you drag near an edge so you can select something bigger than what's on screen.
 
🔍 Auto-extract numbered questions
PromptDock scans the PDF text and detects numbered questions automatically (1., 2), Q1., or plain table-style numbering), resetting the count at each new unit/section. Click any question to send it to the chat as text, or copy it.
 
▶ Autosolve
Point it at your extracted question list and it sends them to ChatGPT one after another automatically — waiting for each answer to finish, cooling down 5 seconds, then moving to the next. Stop it anytime. If one question fails to send, it's skipped so the rest keep going.
 
🔗 Save your chat links
Bookmark the current ChatGPT conversation, tagged to the PDF and page you were working from, so you can find your way back to a module and its answers later.
 
PRIVACY
